Hi, Could you please support or at least add to the documentation input groups. These are super useful in user account sections and forms. I know that you have icon prefix option but its just not the same. here is the bootstrap 4 docs that have great examples https://getbootstrap.com/docs/4.0/components/input-group/ The code below is to get you started or even drop it right into the documentation. And when 4.4.2 comes out you can even style it a little better

<div class="form-control-group">
 <label for="basic-url">Your vanity URL</label>
<div class="input-group">
 <span class="input-group-addon" id="basic-addon3">https://example.com/users/</span>
 <input type="text" class="form-control" id="basic-url" aria-describedby="basic-addon3">
</div>
</div>
